I had a smart meter once. They cut off my air-conditioner any time it got really hot. The idea was they’d cut it off during peak periods for “up to 15 minutes.” Then, they’d let your air conditioner run; you “won’t know it’s happening.” Well, at 100 degrees and 100% humidity, I timed it; or, started to. But it went off and stayed off. I called the centric company. Somewhere in the fine print it said that they could do whatever they pleased. I had it removed.
There’s a power problem? Build a couple of coal fired power plants. Problem fixed.
I am curious. How did they shut off your air conditioner without shutting off the power for rest of the house?
